Bonjour à tous,

Dans un précédent message, je parlais des possibilités futures de
recherches contextuelles sur des textes présentés sous format image.
Voici les références que j'avais en tête concernant le serveur Gallica:

Originally conceived by William G. Bowen, President of The Andrew W. Mellon
 Foundation, JSTOR began as an effort to ease the increasing problems faced by
 libraries seeking to provide adequate stack space for the long runs of
backfiles of
 scholarly journals. The basic idea was to convert the back issues of paper
journals into
 electronic formats that would allow savings in space (and in capital costs
 with that space) while simultaneously improving access to the journal
content. It was
 also hoped that the project might offer a solution to preservation
problems associated
 with storing paper volumes.

 To demonstrate the concept, the Mellon Foundation sponsored a pilot project to
 provide electronic access to the backfiles of ten journals in two core
fields, economics
 and history. Five library test sites were selected initially. Every issue
of the ten
 participating journals published prior to 1990 -- approximately 750,000
total pages --
 has now been converted from paper into an electronic database that resides
at the
 University of Michigan and is mirrored at Princeton University. Using
 developed at Michigan, high-resolution (600 dpi) bit-mapped images of each
page are
 linked to a text file generated with optical character recognition (OCR)
software which,
 along with newly constructed Table-of-Contents indexes, permits complete
search and
 retrieval of the journal material.

 Initial users of JSTOR were enthusiastic, and it was evident that the
concept had great
 promise. Linking a searchable text file to the page images of the entire
 record of a journal offers a level of access previously unimaginable.
Authorized users
 are able to view and print articles using standard PC equipment at any
time and from
 any networked location. Issues of journals are never "out"; they are
always available,
 and in pristine condition. In sum, the addition of powerful search and
 capabilities makes the JSTOR system more than just a way for libraries to
save capital
 costs; it has become a scholarly tool of enormous potential value.

 JSTOR was established as an independent not-for-profit organization in
August 1995.
 The Mellon Foundation has provided JSTOR with its initial working capital,
 is now expected to become self-sustaining.

 In the broadest sense, JSTOR's mission is to help the scholarly community take
 advantage of advances in information technologies. In pursuing this
mission, JSTOR
 has adopted a system-wide perspective, taking into account the sometimes
 needs of libraries, publishers, and scholars.

 JSTOR's goals include the following:

       To build a reliable and comprehensive archive of important scholarly
       To improve dramatically access to these journals
       To help fill gaps in existing library collections of journal backfiles
       To address preservation issues such as mutilated pages and long-term
       deterioration of paper copy
       To reduce long-term capital and operating costs of libraries
associated with the
       storage and care of journal collections
       To assist scholarly associations and publishers in making the
transition to
       electronic modes of publication
       To study the impact of providing electronic access on the use of
these scholarly
