The EndNote program is now available in a free version. https://endnote.com/product-details/basic/
I highly recommend this program to anyone writing scientific papers. It is a relational database that generates footnotes or endnotes and inserts them into Microsoft Word documents. It generates the endnotes in a wide variety of formats. It keeps track of the numbers and arranges them in groups such as "[2, 4-8]." You can see examples in this paper: http://lenr-canr.org/acrobat/RothwellJcoldfusionb.pdf Ed Storms uses it, and used it to organize most of the items in the LENR-CANR.org database. I use it to maintain the database. I wrote a program to convert from the EndNote format to the online relational database. - Jed
