Dear Mailing List, sorry, this email is not really related to tetex but i hope to obtain some help. i am looking for a tool to maintain bibtex files with the following requirements: -fancy user interface with possibility to assign keywords to references -preferable running under unix/linux -creates a database which is accessable via sql-queries the only tool which seems to have these properties and which i encountered is called obas. unfortunately, this tool has many bugs which aren't acceptable. i tried to contact the creator of this tool without success )-: i would really appreciate any pointers and suggestion regarding this issue (other mailing lists, urls ...). many many thanks in advance -- All the best Chris
