Besides the macros supplied with OCLC Connexion Client (I specify the Client because I haven’t worked extensively with the Web interface–any who have, please add your thoughts), there are many more available for you to add.

We’re lucky in the Chicago area to have two of the most productive macro experts in the North Suburban Library System–Joel Hahn of the Niles Public Library District and Harvey Hahn, of Arlington Heights Memorial Library until his recent retirement. Walter F. Nickeson of the Rochester University Libraries and Merry Morris have also contributed numerous macros.

So, where to find them? OCLC’s Connexion Client macros page includes links to Joel Hahn’s macros, Merry Morris’ simple macros, and Walt Nickeson’s macros; the Connexion Client guide Basics: Use Macros (also listed below); macro lessons for beginners; and materials from Harvey and Joel Hahn’s June 2005 ALA session on using Connexion macros.

Want to go deeper? Basics: Use Macros is a huge resource with which you can spend many happy hours. It includes extensive instructions on the creation and use of macros with OCLC Connexion.

One caution that I’ll mention here: Create your own macro book or books for any new or modified macros you bring into Connexion, whether you create the macros yourself or find them elsewhere. The two OCLC-supplied macro book files, OCLC.mbk and Dewey.mbk, may be overwritten during Connexion software upgrades, and if that happens you’ll lose anything of yours that was stored in those books.

And one more useful resource: Joel Hahn’s Better Living through Macros includes step-by-step instructions for loading macros into Connexion from various sources and “OCLC Macro Language for the Complete Beginner” (OML is a Basic-derived programming language).
