### Additional Services

_Component Description_: There are a number of additional CDRS-provided services that distinguish _Tremor_ from other journal publishing projects in the center. Examples include, the work of Communications staff to develop and produce marketing material; APC and vendor invoice processing through the library’s business office; archiving and preservation of journal content in the university’s digital research repository; and development of journal-specific data management policy. Where the affordances of the areas of activity within CDRS and the libraries broadly have provided opportunity for expansion of the journal’s operations, these activities have been captured under Additional Services. 

_Project Specifics_: Midway through the reported project period, _Tremor_’s editor initiated conversation with the patient-advocacy group Tremor Action Network (TAN). These discussions produced additional financial support for _Tremor_ in the form of TAN-sponsored publication scholarships. Authors submitting to _Tremor_ could always elect to have the APCs waived by responding to select questions about available sources of funding. Through the TAN scholarships, however, an additional source of publication support is made available. (See Figure \ref{fig:waivschol} for an accounting of waivers and scholarships granted over the life of the journal.) Oversight of the waivers and the scholarship applications adds a level of administrative overhead for both CDRS and the libraries office, and these costs begin tracking in 2012.

_Expense Overview_: Costs under Additional Services are borne largely by three groups: the business office as it processes APC invoices and manages _Tremor_’s accounts; Communications, as it facilitates outreach through custom mailings and other forms of journal promotion; and through the junior staff in Production, preparing internal reports, archiving journal content, onboarding new services such as DOI assignment and more. With some minor variation, these costs are relatively steady across years and comprise approximately 7.6% of the overall estimated journal costs. _Tremor_’s role within the center as an ambassador for the program suggests these costs will remain steady over time, and perhaps higher in comparison with future journals as efficiencies are realized through experience (Figure \ref{fig:addlservicesgraph}).
