Issuu is a website that allows you to collect, share and publish your work in its intended designed format. No generic layouts. Embedded web urls are allowed and it is cool to watch your pages turn ;-). Most importantly though, it provides this zoom feature that will let you show off your typographic details that cannot usually be showcased in a low-resolution pdf.
Here are a few screen shots of a few spreads but exploring an interactive one by going to the site is way more fun!
Share with us if you have other (better) resources for online portfolios and/or if you publish your own work using Issuu!
