Search the Internet for References Search PubMed and Internet libraries worldwide from ProCite. Export references directly from Web of Science, Current Contents and Discovery Agent. Build your personal reference collection from hundreds of diskette, CD-ROM, Online and Web databases – reduce data entry. Manage Your References Organise your data using standard Windows and Macintosh navigational tools in ProCite. Link to the World Wide Web and capture Web pages into your ProCite database. Locate references in seconds with powerful searching options, such as contains, empty/not empty and more. Save search expressions and re-use them later. Create reference groups to identify a specific subset of a database.


EndNote connects to Internet-based libraries of reference data (there are many free-access databases in addition to those that your organization or institution subscribes to) and locate the references for citation. EndNote stores, catalogues and indexes these references in your own custom reference databases, together with images, figures, files and links that you want to include or cite. And EndNote integrates into your word processor to make it easy to insert citations and create bibliographies and figure lists, with every entry automatically and consistently formatted in the style you, or your publishers, prefer.



Bibster is a Java-based system which assists researchers in managing, searching, and sharing bibliographic metadata (e.g. from BibTeX files) in a peer-to-peer network.

Specify Software Project

Specify is a research software application, database, and network interface for biological collections information. It manages specimen data such as descriptions of collecting locations, participants and determination histories as well as information about collections transactions such as loans, exchanges, accessions and gifts.



GPSPhotoLinker can be used to save location and GPS position data to a photo. The latitude and longitude recorded by your GPS unit while you were taking photos can be linked, and saved, to the photos. GPSPhotoLinker automatically enters the city, state and country into the metadata.




The AnimalBase database is primarily established to link the old literature with the names of the animals described therein. We have continuously gone through the old works, from 1757 onwards, and entered all correctly described new animal names (genera and species taxa) by hand according to a standard established by our working group. Today the database should include all zoological taxa described from 1757 until 1770. The names are entered into the database along the original literature and largely independently from other databases and secondary literature sources, so that errors will not be duplicated.


DIVA-GIS is a free and open source geographic information system (GIS) to make maps of species distribution data and analyze these data.


Xper2 is a flexible and powerful knowledge management tool that helps users make an identification or diagnosis. It is a complete system that can performs management of descriptive data (creation of knowledge databases), and offers many associated tools in order to analyse those descriptive data (control and prevent of inconsistencies, comparison and analysis of taxonomic descriptions, summary of the base). Xper2 has an Editor and a Player for creating and deploying identification keys (free acces keys).


SLIKS is a small Javascript program that I developed to facilitate the use of interactive keys. It runs over the web or locally on your machine.


PICKEY (Pictured Interactive Computerized biological KEY) is an interactive multi-entry polychotomous key for identification of organisms by intensive use of images. PICKEY is a most user-attractive part of the package BIKEY, which include a large set of programs for creation, analysis and subsequent perfection of computer keys, the initial information for this programs is stored in the form of data bases of most widespread and accessible format DBF for systems FoxPro, dBASE, FoxBase, Clipper, etc.


Lysandra is a software for creating keys and database on different groups of living organisms.


PANDORA is a database system for taxonomic and biodiversity research projects, such as floras or monographs.


Create key from Delta files. Rachis is an open-source application for the arrangement of entities in a hierarchical system (taxonomy), and an interactive key for the entities in that system. The development of Rachis is in a very early stage at the moment, but progressing at a reasonable pace.

Linnaeus II


Linnaeus II is an innovative multifunctional research tool for systematists and biodiversity researchers, facilitating biodiversity documentation and species identification.

Linnaeus II was developed by ETI BioInformatics at the University of Amsterdam, the Netherlands. The software package, available for both Windows and Mac OS X, allows the creation of taxonomic databases, optimizes the construction of easy-to-use identification keys, expedites the display and comparison of distribution patterns, and promotes the use of taxonomic data for biodiversity studies.

The software can also be used to publish completed information systems on CD-ROM / DVD-ROM or make them available on the Web.



NaviKey is a Java applet and application for accesssing descriptive data coded in DELTA format and has been implemented as:
  • a Java applet providing the contents of DELTA files (see example with the DELTA sample data files)
  • a stand-alone Java application for accessing DELTA files or PostgreSQL versions of DiversityDescriptions databases, respectively
  • a module ("plug-in") of the Java-based Diversity Navigator database client for accessing DELTA files or PostgreSQL versions of DiversityDescriptions databases, respectively

The Electronic Field Guide (EFG) Project

The Electronic Field Guide (EFG) Project has developed a number of web-based applications that facilitate the identification of species and recording of ecological observations. This project is the result of a collaborative effort between the Departments of Computer Science and Biology at the University of Massachusetts Boston, with funding from the National Science Foundation.


Lucid is a flexible and powerful knowledge management tool that helps users make an identification or diagnosis. Lucid3 is an entirely new implementation of the Lucid family of products, providing new features requested by Lucid users and improving the handling of many common functions. The Lucid3 system comprises a Builder and Player for creating and deploying effective and powerful identification and diagnostic keys. The Lucid3 Builder allows an expert in a group of entities (plants, animals, diseases, minerals, archaeological artifacts etc) to create a key that can be deployed over the World Wide Web.

DiversityDescriptions (DeltaAccess)

A SQL interface to DELTA, the Description Language for Taxonomy, implemented in Microsoft Access 97, 2000, and 2002 (= XP). DeltaAccess can be used in 3 ways: a) You can use DeltaAccess simply as a module to import DELTA coded text files into a database of your choice and then write an independent application for that database (e. g. a web interface). b) You can keep your data in DELTA coded text files, and use DeltaAccess as a one-way import tool to analyze your data (incl. cross-tabulations, and charts), print form sheets to edit your data off-line, or to generate dynamic html/www output. c) You can use DeltaAccess as the central data repository around which your work is organized.
