EndNote x1 Limitations

Hi, I wanted to know what are the limitations for EndNote X1, as in, up to how many records/references I can add to my library before it becomes too much and affects my performance, and if the data will get corrupt once I reach a certain (excessive) number of references? 


How about some quantitative data colection?  I usually use EndnoteX and am rather selective as to what ends up in my library. 

I have just under 5000 records, maybe less than 20% have a pdf attached (10% in the “figure” spot and the other 10% in the PDF spot).   

And have been using Endnote since it was a DOS program from Niles.  Can’t remember WHEN that was!

Since version 8, the ceiling of records was wiped out and there is no maximum for a single library (or multiples)

A faculty member here recently sent a testimonial; she and her grad assistants created a library in less than one year with more than 10,000 entries organizing references providing meta-analysis of a particular topic in all disciplines…  and she is a new user…

I’m sure there are longtimers who have even more records…

have a nice day,


Virginia is correct. Since version 8 EndNote has been technically “unlimited” in file size or number of records. Admittedly, “unlimited” is a pretty hard number to verify but we routinely test internally with libraries with as many as half a million records with no issues. As with most other applications, EndNote’s performance with large files will be substantially impacted by an individual computer’s processor speed and available memory.
