I do not understand why people typically have the annotation in a separate file than the drawing. Then they are xref'd into a sheet file. Can someone tell me the benefits of separating drawings, annotations, and sheet files?

Let me start with the terminology my company uses which is a little different then what are using. We are a civil engineering firm that does land development, transportation, water resources, and survey among other things.
We have design drawings and sheet drawings. Design drawings contain all the line work for the project, including survey points, existing conditions, proposed site layout, contours, etc. The sheet drawings are the plans that we submit for review, approval and construction.
Most of these design drawings have very little text. The exception is the survey layout drawing which is used as the plat base. It includes lot numbers, road names and all of the labeling for the parcel segments. Basically everything that is need on the final plat.
A typical LD project will have several design drawings. We have separate design drawings for points, profiles, contours, streets and utilities (one drawing) and within those categories we separate existing and proposed.
To create a sheet drawing, water plan for example, we will xref in the required design drawings and label the pipe and structures in the sheet drawing. This drawing will contain a title block in paper space along with north arrow, scale, notes, etc.
Now to answer your question. There are two main advantages to this procedure. It easier for multiple people to work on the project at one time. And it keeps the sheet drawing file sizes to a minimum by not requiring us to xref data that is not required for the plan, such as points or contours in a water plan.
As you can see we do not a separate drawing for annotation. I assume that would again make the files sizes smaller if the annotation is not required in all drawings.

In the AEC realm it makes it easier for architects to create enlarged plans. Of course, the recent addition of annotative scaling as made this unnecessary.

I'm not sure about that. I would prefer to go with Jeff's example. It makes it easier to setup and delegate drawings to multiple users.

I think both examples are valid. Most of our clients (Architects) use base files for thier plans, section and elevations then add thier annotation in the sheet file. Maybe it's a midwest thing.

But I'm not from the Midwest. I just find it easier to put the annotation on the sheet it belongs to. It also reduces layer problems with reference drawings.

I meant my example must be a midewest thing. Anyway, I don't think there's a right way or a wrong way. I think a major factor is what industry your in. Fortunately for me, structural doesn't usually get that complicated.
