DELTA Newsletter Archive |
23 January 2011
The DELTA Newsletter was intended to promote communication among scientists developing and applying computer technology in the collection, storage, analysis, and presentation of descriptive taxonomic data. It was not restricted to software or applications supporting or implementing the DELTA Standard.
Topics included: computer programs for taxonomy, data formats, data interchange standards, data capture, data analysis, database design, description printing, expert systems, information retrieval, interactive identification, key making, mapping systems and taxonomic characters.
Only Numbers 8–12 were available in electronic form. I scanned hard-copy versions of Numbers 1–7, processed them with OCR, reformatted them, made minor corrections, and saved them in HTML and PDF formats. The first two links for Numbers 1–7 access these versions. The third link (‘facsimile version’) accesses the scans; note that these are much larger than the reformatted versions. There may also be a fourth link, to a facsimile version of the list of subscribers.
