I have been writing aphorisms for the most part of my life. Up to now, I noted them down in (real-life, paper) notebooks. From time to time I copied them to a MS-Word-file, which has now swollen to about 100 pages. To cut it short, since I keep on producing and am now also keen on arranging them into collections, sections... it would probably smart to find a better way to collect these bits.

In practice I am looking for an application, that would allow me to collect these aphorisms as single "files" or "quotes", reject duplicates, sort the "files" alphabetically, rearrange them into subcollections, and maybe most importantly: export them to printable formats like docx, odt, pdf, ...

I am aware, that most reference managers would in some way offer at least a part of these functionalities, but that which I tried are still very limited when it comes to e.g. clarity of arrangement. I hope somebody has some experience on the subject!

PS I'm on Mac OS 10.12
