Hello friends, After some quick searching in DYABOLA by author and keyword, I would have to conclude that the free version and the subscription version are by no means identical on every search. In fact, the subscription version w/ Brinkmann is the Catalogue of the Deutches Archaiologisches Institut in Rome, while that of ZENON DAI free site is actually the combined catalogues of not only the DAI in Rome, but in other locations including Istanbul, Athens, Cairo, Madrid, and much more. Thus results don't match much of the time. Sometimes the subscription site has more entries than the free catalogues; other times, it has less. Here are my test results for a few searches: Author: Harrison, E.B. Sub - 53 results ZENON - 53 Smith, T.J. Sub- 10 results ZENON - 9 (missing the latest publication from 2004) Keyword: Parthenon Sub- 444 results ZENON - TITLE - 468 ZENON - ALL - 553 Parthenon frieze Sub- 36 results ZENON - TITLE - 56 Now, note on the keyword searches in ZENON that the first results returned were all undated and unfinished catalogue entries. Thus, for Parthenon, the first 128 entries were old material and unfinished records, so actually the results for that search were 340 and the latest material did not appear until #130. It was frustrating. My present stance on this is to be cautious. I will not give up the subscription just yet, but use both. At least ZENON is easy to print and can email; I will use it more however, for authors than for keyword and titles. Hope this helps and not hinders the discussion. yours, lucie Lucie Wall Stylianopoulos Acting Head, Fiske Kimball Fine Arts Library Collections & Instruction Librarian Librarian for Art/Archaeology, Architecture and Drama University of Virginia Bayly Drive Box 400131 Charlottesville, VA 22904-4131 [log in to unmask] __________________________________________________________________ Mail submissions to [log in to unmask] For information about joining ARLIS/NA see: http://www.arlisna.org/join.html Send administrative matters (file requests, subscription requests, etc) to [log in to unmask] ARLIS-L Archives and subscription maintenance: http://lsv.uky.edu/archives/arlis-l.html Questions may be addressed to list owner (Judy Dyki) at: [log in to unmask]
