Hi, thanks for asking!
Strictly speaking, the Googlebot isn't "our" spider. We're Google
Answers, independent Researchers, working on contract. We don't speak
officially for the Google Search Engine. However, we're happy to
assist you, based upon personal experience, web research, and
knowledge.
Your Dreamweaver Library item is simply the page header. It is
expected that websites use some type of header logo and links that
identify the site, and provide consistent navigation. It's considered
one of the hallmarks of professional website design.
As long as you also have differing text content on every page, there's
nothing about a consistent logo and header that would create a barrier
to site indexing by Google.
The Yale C/AIM Style Guide proclaims such consistency as a necessity
of site design. "Establish a layout grid and a style for handling your
text and graphics, then apply it consistently to build rhythm and
unity across the pages of your site. Repetition is not boring; it
gives your site a consistent graphic identity that creates and then
reinforces a distinct sense of "place" and makes your site memorable.
A consistent approach to layout and navigation allows readers to adapt
quickly to your design and to confidently predict the location of
information and navigation controls across the pages of your site."

As long as you are creating identical page elements to serve users,
rather than search engine spiders or bots, you're following the Google
Webmaster Guidelines. Google doesn't specify a specific percentage of
'differing content' however, legitimate content with fixed page
headers, footers, and other navigation aids, changing from page to
page within a single website is the norm, not the exception. 20%
page-to-page changeable content would be considered a very safe
margin.
Google's Quality Guidelines state, "Make pages for users, not for
search engines." "Another useful test is to ask, "Does this help my
users? Would I do this if search engines didn't exist?" If the answer
to both questions is yes, then you're on the right track.

I apologize, I cut (or rather didn't paste) a portion of my answer.
---------------
Dreamweaver Library items are handled as page includes, similar to the
way Server Side Includes (SSI) are processed as web pages are
delivered from the server. All the links within the library items will
be catalogued in that assembled page code. The search engine "reads"
the assembled page. It doesn't matter how many individual parts the
page has.
This method, of course, conserves server space, and can also speed up
user page download, as identical elements are cached and reused by the
browser.
The beginning and library tags are comments for your own reference.
They show where content has been inserted from the Dreamweaver
Library. They're ignored by the server and the search engine spiders.
Dreamweaver Instructions for update of Library items:
To update the current document to use the current version of all
library items:
Choose Modify > Library > Update Current Page.
To update the entire site or all documents that use a particular
library item:
1 Choose Modify > Library > Update Pages.
The Update Pages dialog box appears.
2 In the Look In pop-up menu, do one of the following:
Choose Entire Site, and then choose the site name from the adjacent
pop-up menu. This updates all pages in the selected site to use the
current version of all library items.
Choose Files That Use, and then choose a library item name from the
adjacent pop-up menu. This updates all pages in the current site
that use the selected library item.
3 Make sure Library Items is selected in the Update option. (To
update templates at the same time, make sure Templates is also
selected. See Updating pages based on a template for more
information.)
4 Click Start.
Dreamweaver updates the files as indicated. If you selected the
Show Log option, Dreamweaver provides information about the files
it attempts to update, including information on whether they were
updated successfully.
