A Library to Last Forever

A Library to Last Forever

Published: October 8, 2009

“THE fundamental reasons why the electric car has not attained the popularity it deserves are (1) The failure of the manufacturers to properly educate the general public regarding the wonderful utility of the electric; (2) The failure of [power companies] to make it easy to own and operate the electric by an adequate distribution of charging and boosting stations. The early electrics of limited speed, range and utility produced popular impressions which still exist.”

This quotation would hardly surprise anyone who follows electric vehicles. But it may be surprising to hear that in the year when it was written thousands of electric cars were produced and that year was nearly a century ago. This appeared in a 1916 issue of the journal Electrical World, which I found in Google Books, our searchable repository of millions of books. It may seem strange to look back a hundred years on a topic that is so contemporary, yet I often find that the past has valuable lessons for the future. In this case, I was lucky — electric vehicles were studied and written about extensively early in the 20th century, and there are many books on the subject from which to choose. Because books published before 1923 are in the public domain, I am able to view them easily.

But the vast majority of books ever written are not accessible to anyone except the most tenacious researchers at premier academic libraries. Books written after 1923 quickly disappear into a literary black hole. With rare exceptions, one can buy them only for the small number of years they are in print. After that, they are found only in a vanishing number of libraries and used book stores. As the years pass, contracts get lost and forgotten, authors and publishers disappear, the rights holders become impossible to track down.

Inevitably, the few remaining copies of the books are left to deteriorate slowly or are lost to fires, floods and other disasters. While I was at Stanford in 1998, floods damaged or destroyed tens of thousands of books. Unfortunately, such events are not uncommon — a similar flood happened at Stanford just 20 years prior. You could read about it in The Stanford-Lockheed Meyer Library Flood Report, published in 1980, but this book itself is no longer available.

Because books are such an important part of the world’s collective knowledge and cultural heritage, Larry Page, the co-founder of Google, first proposed that we digitize all books a decade ago, when we were a fledgling startup. At the time, it was viewed as so ambitious and challenging a project that we were unable to attract anyone to work on it. But five years later, in 2004, Google Books (then called Google Print) was born, allowing users to search hundreds of thousands of books. Today, they number over 10 million and counting.

The next year we were sued by the Authors Guild and the Association of American Publishers over the project. While we have had disagreements, we have a common goal — to unlock the wisdom held in the enormous number of out-of-print books, while fairly compensating the rights holders. As a result, we were able to work together to devise a settlement that accomplishes our shared vision. While this settlement is a win-win for authors, publishers and Google, the real winners are the readers who will now have access to a greatly expanded world of books.

There has been some debate about the settlement, and many groups have offered their opinions, both for and against. I would like to take this opportunity to dispel some myths about the agreement and to share why I am proud of this undertaking. This agreement aims to make millions of out-of-print but in-copyright books available either for a fee or for free with ad support, with the majority of the revenue flowing back to the rights holders, be they authors or publishers.

Some have claimed that this agreement is a form of compulsory license because, as in most class action settlements, it applies to all members of the class who do not opt out by a certain date. The reality is that rights holders can at any time set pricing and access rights for their works or withdraw them from Google Books altogether. For those books whose rights holders have not yet come forward, reasonable default pricing and access policies are assumed. This allows access to the many orphan works whose owners have not yet been found and accumulates revenue for the rights holders, giving them an incentive to step forward.

Others have questioned the impact of the agreement on competition, or asserted that it would limit consumer choice with respect to out-of-print books. In reality, nothing in this agreement precludes any other company or organization from pursuing their own similar effort. The agreement limits consumer choice in out-of-print books about as much as it limits consumer choice in unicorns. Today, if you want to access a typical out-of-print book, you have only one choice — fly to one of a handful of leading libraries in the country and hope to find it in the stacks.

Readers' Comments

I wish there were a hundred services with which I could easily look at such a book; it would have saved me a lot of time, and it would have spared Google a tremendous amount of effort. But despite a number of important digitization efforts to date (Google has even helped fund others, including some by the Library of Congress), none have been at a comparable scale, simply because no one else has chosen to invest the requisite resources. At least one such service will have to exist if there are ever to be one hundred.

If Google Books is successful, others will follow. And they will have an easier path: this agreement creates a books rights registry that will encourage rights holders to come forward and will provide a convenient way for other projects to obtain permissions. While new projects will not immediately have the same rights to orphan works, the agreement will be a beacon of compromise in case of a similar lawsuit, and it will serve as a precedent for orphan works legislation, which Google has always supported and will continue to support.

Last, there have been objections to specific aspects of the Google Books product and the future service as planned under the settlement, including questions about the quality of bibliographic information, our choice of classification system and the details of our privacy policy. These are all valid questions, and being a company that obsesses over the quality of our products, we are working hard to address them — improving bibliographic information and categorization, and further detailing our privacy policy. And if we don’t get our product right, then others will. But one thing that is sure to halt any such progress is to have no settlement at all.

In the Insurance Year Book 1880-1881, which I found on Google Books, Cornelius Walford chronicles the destruction of dozens of libraries and millions of books, in the hope that such a record will “impress the necessity of something being done” to preserve them. The famous library at Alexandria burned three times, in 48 B.C., A.D. 273 and A.D. 640, as did the Library of Congress, where a fire in 1851 destroyed two-thirds of the collection.

I hope such destruction never happens again, but history would suggest otherwise. More important, even if our cultural heritage stays intact in the world’s foremost libraries, it is effectively lost if no one can access it easily. Many companies, libraries and organizations will play a role in saving and making available the works of the 20th century. Together, authors, publishers and Google are taking just one step toward this goal, but it’s an important step. Let’s not miss this opportunity.

브라우저란 무엇인가


뉴욕 타임스퀘어에서 50명의 사람들에게 "브라우저란 무엇인가?" 에 대해 물었다.
각기 다른 대답들.
굳이 자동차에 가솔린이 들어가서 어떻게 동작되는 지를 몰라도 운전을 하듯이,
사람들에게 '정의'는 중요치 않은 것 같다.
그보다는 그들이 어떻게 '브라우저' 를 이용하고 느끼고 있는지가 중요한듯하다.

방통위, 스마트폰에 와이파이 채택 유도키로

  방송통신위원회는 스마트폰 보급 확산 및 모바일인터넷 시장 활성화를 위해 이동통신업체들에게 스마트폰을 포함한 휴대폰에 와이파이(Wi-Fi) 접속기능을 기본적으로 탑재토록 유도하기로 했다고 밝혔다.


이는 이동 중에는 이동통신망을 이용해 모바일인터넷을 이용하거나 착신전환 등으로 와이브로 서비스를 이용하고, 고정된 곳에서는 와이파이를 통해 유선 초고속인터넷을 무료로 이용할 수 있는 환경을 마련하겠다는 취지라고 방통위는 설명했다.

이를 통해 이용자는 요금에 대한 부담을 상당부분 줄이면서 무선인터넷을 자유롭게 이용할 수 있고, 이통업체는 성장이 정체된 음성통화 매출의 문제를 극복하고 새로운 시장을 창출하는 효과가 있을 것이라고 방통위는 말했다.

한편 방통위는 휴대폰 이용자가 음원, 게임, 동영상 등 휴대폰용 컨텐츠를 PC로 우선 다운로드한 후 이를 휴대폰으로 전송하는 이른바, 사이드로딩(Side loading)을 전면적으로 허용토록 하겠다고 밝혔다. 이용자들은 불필요한 무선 데이터통화료를 지불하지 않아도 되고, 컨텐츠제공업체들은 휴대폰용 컨텐츠를 이통사에 종속 받지 않고 판매할 수 있게 된다고 방통위는 말했다.

Wi-fi 기능을 기본적으로 탑재하는 정책을 추구하는 동시에, 사이드로딩의 전면허용을 통한다는것은, PC sync가 정말로 활성화 될 수 있겠다는 생각이 들게 한다.

하루만 기사 빨리나오지....

    Pull-up resistor

    Pull-up resistor

    From Wikipedia, the free encyclopedia

    Pull-up resistors are used in electronic logic circuits to ensure that inputs to logic systems settle at expected logic levels if external devices are disconnected. Pull-up resistors may also be used at the interface between two different types of logic devices, possibly operating at different power supply voltages.

    The idea of a pull-up resistor is that it weakly "pulls" the voltage of the wire it's connected to towards 5V (or whatever voltage represents a logic "high"). However, the resistor is intentionally weak (high-resistance) enough that, if something else strongly pulls the wire toward 0V, the wire will go to 0V. An example of something that would strongly pull a wire to 0V would be the transistor in anopen-collector output.

    Similarly, pull-down resistors are used to hold the input to a zero (low) value when no other component drives the input. They are used less often than pull-up resistors. Pull-down resistors can safely be used with CMOS logic gates because the inputs are voltage-controlled. TTL logic inputs that are left un-connected inherently float high, thus they require a much lower valued pull-down resistor to force the input low. This also consumes more current. For that reason, pull-up resistors are preferred in TTL circuits.

    In bipolar logic families operating at 5 VDC, a typical pull-up resistor value will be 1000–5000 Ω, based on the requirement to provide the required logic level current over the full operating range of temperature and supply voltage. For CMOS and MOS logic, much higher values of resistor can be used, several thousand to a million ohms, since the required leakage current at a logic input is small.

    A circuit showing a pull-up resistor (R2) and a pull-down resistor (R1)

    Pull-up resistors may be used at logic outputs where the logic device cannot source current, such as open-collector TTL logic devices. Such outputs are used for driving external devices, for a wire-OR function in combinatorial logic, or for a simple way of driving a logic bus with multiple devices connected to it. For example, the circuit shown on the right uses 5 V logic level inputs to actuate a relay. If the input is left unconnected, pull-down resistor R1 ensures that the input is pulled down to a logic low. The 7407 TTL device, an open collector buffer, simply outputs whatever it receives as input, but as an open collector device, the output is left effectively unconnected when outputting a "1". Pull-up resistor R2 thus pulls the output all the way up to 12 V when the buffer outputs a "1", providing enough voltage to turn the power MOSFET all the way on and actuate the relay.

    Pull-up resistors may be discrete devices mounted on the same circuit board as the logic devices. Many microcontrollers intended for embedded control applications have internal, programmable pull-up resistors for logic inputs so that minimal external components are needed.

    Some disadvantages of pull-up resistors are the extra power consumed when current is drawn through the resistor, and the reduced speed of a pull-up compared to an active current source. Certain logic families are susceptible to power supply transients introduced into logic inputs through pull-up resistors, which may force the use of a separate filtered power source for the pull-ups.

    [edit]I²C

    Pull-up resistors are needed on the clock and data line for an I²C circuit because they are open-collector pins on the chips

    I²C requires pull-up resistors on its clock (SCL) and data line (SDA) because the pins on the chips are of open-collector design. This means that a chip can only pull the lines low, otherwise they float up to VDD. In I²C, pulling the line to ground indicates a logical zero while letting it float to VDD is a logical one. As a channel access method, this allows one node to determine if another is transmitting by sensing that when asserting a logical 1 (letting it float) and sensing if the line is still at a logical 1 (no other node is pulling the line to ground) then it's possible no other node is simultaneously transmitting. However, if a second node pulls the line to zero then the first node can detect that the other is transmitting.
