I have Zotero installed in my browser, so logging a Blogger citation entry was as simple as Click- 1-2-3.
I'm using Firefox, and I'm on an iMac. When I'm viewing a Blogger page, a small blue icon appears to the left of the favorites star in the browser address bar. (See the small blue icon circled in the graphic below.)
Clicking on that small blue icon saves the citation metadata as a "blog post" (item type) to Zotero. The metadata saved includes the TITLE of the blog post, DATE of the blog post viewed, the post AUTHOR, the BLOG NAME, web address or URL, and ACCESS DATE.
Isn't this cool! But wait, there's more....
Since the data is saved as a "blog post," once Zotero has captured the metadata, it's a simple 1-2-3 to capture/store an image of the web page and slide the citation into Microsoft Word (for me, that's Microsoft Word 2011 for Mac).
With the blog entry selected (Zotero displays the image #1 in the graphic), I click the paperclip icon on the Zotero toolbar (item 2, circled in red)--Zotero saves a digital version of that relevant blog entry/page as an attachment to the citation entry. (The image attached to my entry has just a little different background than blog page, see the graphic.)
Oooo, don't you love it.
I simply drag the listed citation entry (not shown in the graphic) to Microsoft Word 2011, and it formats a citation (see #3 in the graphic).
I would probably dress up the formatting (Bear is a big EE fan) and add some additional references, but for Click 1-2-3, I'm more than pleased about this Zotero-Blogger relationship.
*Note: This worked "out of the box" for blog entries on the front page. To support archived blog postings, I had to update the Blogger.js file in my Mac folder, User>Library> Application Support> Firefox>Profiles>xxx.default>zotero>translators . See the link here for the update input I used.
